tty present invention relates to improvements in cattle guards ttor usealongpuhlic and private highway crossii'igs to prevent cattle and othersteelt trein trespass-ring upon the rip it oit Way ot a railway. guardhai-hed, or studded, hars that are removably journaled, transversely otthe railroad.7 in guard r(f extending); parallel with the traelr rails.

.its herein illustrated and described the iro-- tary liars are located.hete/*een the tract: 'rails and at the trac-lr side, or along@` the ou ci sides et the track, and they are arranged in sec tions, hut it willloe understood that other arrangements inay he inade it des rei` i lierotary, hat ,ed liars., however are liioued in quantities ot eiinilarsise and shape and they are capable olf use at t' "'erent places withrelation to the traclr rai The cattle ruard is coinposcd c ntially otbut ttvo elements. the guard iails 1nd the `rotary hars, and these partsmay he cast troni Iiiolten scrap inetah thus reducing; their cost otproduction, rendering@` them etsy to crush under the Weight el' ainovine train. Without danger oit derailingi' the traiin and 'yetproifidintf the rcrpiired strength to sus tain the Weight oittrespassinp steelt.

rlhe reinovalile rotary hars are jtairnaled in pairs of parallel railhars or jituard rails in such manner as to permit their unict; and easyrenioval 'when necessary to tanip or otherwise repair the road hed, ortor the purpose oit clearing' the track or traclts to permit cattle tohe driven across the track. llhe stationary guard rails are ailizted, ashy lap; screws7 to the cross ties in such inanner as to he readilyremovable it and when it is necessary to repair or replace the underlying; ties.` llue to the ininiinurn nuinloer of parts used and to thesimplicity in construeu tion and operation ot the cattle guard ot niyinventioru it has proven highly successtul and satisfactory in actualuse on railroads7 and is new being used under thes successtul andsatisfactory conditions.

ll/ly invention `consists in certain novel combinations and arrangementsoi parts involving the stationary guard rails and the rotary studded,har-s or spindles, as will hereinatter he more tally set forth andclaimed.

ln the accompanying drawings I have illustrated one complete example ot'the phys ica-l embodiment ot niy invent-ion wherein the parts areeornhined and arranged ao- The cat le i is oit that type utilizingrotary,`

rordingr to the liest inode I have thus tar devised 'tor the practicalapplication olfthe principles ot n'iy invention.

1 jure `l a plan view, partly broken away, showing; the cattle 4guardapplied lietvveeu the rails and at tlie traclrside ot a railroad. i

lligure 2 is a sectional view at line 2--2 ol" 'l oi a single trackrailroad to which the cattle pfuard is applied.. i

lhe guard rails are designated as l, 2, 3, d, 5, (i, and 'l and they arepreferably cast rails, ol inverted T-sliape and provided 'with aniujirie'lit web as 8 which is ot sul'ticient i height, in the case olthe center rail et, to

support and perinit a fallen hralie beani to ride over its top edgeWithout injury to the cattle guard.

These `guard rails as shown are disposed longitudinally ot the traclrrails and are ot suitable length ior the purpose im' which they areintended. At cquidistant points throughouttli-e length oit theguardrails they are provided with enlargements or lugs some oit which aresingle lues 9 and others double lugs l0. the single lugs beine' locatedat one side ot the weh 8, and the double lugis lacing1 fashioned at hothsides ot the web 8 ot the center guard rail Ll.

idoine oit the single lug-s El (as in rails i2, 3, 5 and G) have roundsockets 1l opening :from one side ol' the rail and sonic of the lugs 9,as rails l and 7 (the outer guard rails at the outside ot the traelr)are provided with, vertically arranged, elliptical sockets l2 and theside walls ot' these elliptical soclrets are provided with open slots13n The double lugs of the center guard rail are also provided withthese sockets 12 and slots 13, at opposite sides of the center Web 8,and the slots 13 at opposite sides of the web opening oppositedirectionsu The guard rails are arranged in pairs, spaced apart asindicated, and secured, as by lag screws to the cross ties, with aseries of round sockets 11 facing a series ot' elliptical sockets 12,and the elliptical sockets at the opposite sides of the center guardrail 1 face series of round sockets in the lues of the guard rails 3 and5 at the inner sides of the track rails R and R.

Between guard rails of a pair a series of rotary, barbed or spiked bars14 are journaled with their end journals 15 in the respective sockets,and the studs 16 on these bars or spindles are arranged in spiralformation,. three spirally arranged series of studs being illustrated inFigure 6.

By the spiral arrangement herein referred to, adjacent groups of spinesare disposed angularly so that the spines are regularly staggered on thebar, the spines of adjacent Agroups being displaced by an angle of 60degrees. Consequently when a cows foot is set upon a spine of one groupso as to turn that spine downward, before that spine has moved more than60 degrees thc adjacent spine of a group on one side or the other, willstrike the side of the cows foot, tending to push the foot sidewise,causing the cow to lift its foot from the descending spine in order toobtain a firmer foothold. Thus the cow will move its foot before itdescends low enough to pass beneath a pair ot spines on adjacent bars,1n

which position the foot would be. irreleasably held resulting in injuryto the cow.

One end 15 is slipped into a socket 11 and the other end of the rotarybar is passed laterally through the slot 13 and deposited in the bottomof the elliptical socket 12 of the opposite guard rail of a pair, andthe rotary bars are spaced apart and arranged in parallelism asindicatedin Figure 1. They may readily be'removed when desired, by slipping onejournal through its slot 13 and then pulling the other journal from itssocket/11.

The parallel rotary bars are spaced apart a sufficientdistance toprevent the hoof of an animal from resting on two bars to prevent theanimal walking on the guard, but. they are sufliciently close to preventthe animals foot from passing through the space between them. When thefoot or hoof is placed between a pair of bars, the studs on therespective bars are turned inwardly loward the hoof to pinch itsutiiciently to cause the animal to withdraw the hoof and back oill theguard.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is- 1. A cattle guard comprising a centerguard rail having s aced double-lugs and clliptical sockets in ticopposite faces of said lugs having open slots, guard rails along theinner sides of the track rails having spaced lugs with round socketstherein, and studded, rotary guard bars having journal ends in saidsockets.

2. A rotary cattle bar for cattle guards comprising an integral castingmade from scrap iron ot' such character as to be breakable under theimpact ol a blow from a` wheel of rolling stock, toi-med with trunnionsat its opposite ends, and intermediatcly formed with laterally extendingblunt spines arranged around thc axis of said bar.

El. A cattle bar for cattle guards comprising a. rotatable spindleprovided with blunt spines projecting radially thereof, arranged ingroups of three, the spines of cach group being equallycircumferentially displaced, the groups being disposed in parallelplanes` perpendicular to the axis of said spindle. and intersecting saidaxis at distance intervals ol' such length as to cause a cows foot whenset upon a spine ot one group to be in the path of movement of spines inan adjacent group, the spines of adjacent groups being arranged at arelative angular displacement of approximately halt the angle betweenthe spines of a group.

In testimony whereof I allix my signature.
